But it's bullshit, because non-N95 masks are effective at protecting the wearer, about half as effective as N95 masks, and if "selfish" people wear masks to protect themselves they will also protect others from themselves. The authorities are feeding the public bullshit to protect mask supply, and the public isn't stupid enough to believe it, but social norms will have to change in the US quite a bit before wearing masks everywhere all time time (even with no pandemic, as is common in many parts of Asia) will become socially acceptable.
